Provided are a rubber or elastomer medical device that is excellent in sliding properties, low protein adsorption properties, low cell adsorption properties, and the durability of these properties (the ability to reduce deterioration of sliding properties, low protein adsorption properties, and low cell adsorption properties), and a method for producing the device. The present invention relates to a rubber or elastomer medical device having a surface treatment layer on at least a part of its rubber or elastomer surface, the surface treatment layer including a functional layer formed of a silane compound containing a polyoxyalkylene group, a metal salt-containing hydrophilic group, a halogen salt-containing hydrophilic group, or a fluorine-containing hydrophobic group.
